Abstract:
A data file management apparatus capable of avoiding the unauthorized deletion of a file shared by a plurality of users. In the apparatus connected to a network and having the function to store the data file in such as to be shared by the users, the address information of the joint file users permitted to share the data file are registered-while being related to the data file at the time of data file storage, and in response to a data file deletion request, a message to confirm the consent of the joint file users about the data file deletion is sent to the registered address information. Upon receiving a message returned from a joint file user not to consent to the data file deletion within a predetermined period from the confirming message transmission, the data file is not deleted, while the data file is deleted otherwise.
